Microplastics

Modeling the vector effect of microplastics in the environment

This project is estimating the vector effect – by which microplastics can absorb organic or inorganic pollutants – and estimating its environmental impact.

Timeline

Underway since March 2019

Additional information

Microplastics can act as vectors for other environmental contaminants, absorbing organic and inorganic pollutants. Previously, there had been no known studies examining this vector effect or related kinetics. The current project aims to construct a model for estimating the vector effect of microplastics and predicting its impact in the environment.
